Custom LASIK uses a technology called "wavefront" to diagnose the unique shape of the patient's cornea, then to create a map that the surgeon can use to perform very precise LASIK adjustments.
The wavefront technology has been around for decades, used by astronomers to adjust the large mirrors in their telescopes to correct for distortions caused by the earth's atmosphere. Only recently has it been applied to the improvement of human vision.
Many surgeons will perform a wavefront diagnostic for all patients requesting vision correction surgery. Not all will use this diagnostic to create the surgical map, either because they do not find it necessary or because the diagnostic shows the patient is not a good candidate for laser surgery.
Great blog! Thanks. I recently had lasik surgery and by accident I stumbled upon www.thepatientsadvantage.com. I used them when looking for a lasik surgeon.
What I liked the most was that my profile remained anynomyous until I was ready to decide what to do. I received replies from four surgeons that met all the things I was looking for. I liked having that complete control without the sales pressure that some of these places can be known for.
If you are going to go down the cosmetic surgery road...better to be safe than sorry. Check them out.
